AAT (Apple Advanced Typography)

Apple Advanced Typography (AAT) is a technology that enhances the way text is displayed on Apple devices. It allows for more precise control of font features, such as adjusting line spacing, kerning (space between characters), and special stylistic options. AAT supports advanced font effects and language-specific typography, enabling high-quality, visually appealing, and readable text across various applications. Think of it as a behind-the-scenes system that ensures fonts are rendered beautifully and accurately, providing a richer typographic experience for users.
